摘　　要：In this paper we will prove some theorems on the M-ideals of compact operators and the best approximation of quasitriangular operator algebras. These results improve and extend the known results in [4, 5, 7].In this paper we will prove some theorems on the M-ideals of compact operators and the best approximation of quasitriangular operator algebras.
